Unit 5 AP Biology Insta-Review (Heredity)

Front

What is the source of mitochondrial DNA mutations?

Back

Mitochondrial DNA mutations are inherited from the mother.

Front

How many rounds of division occur in meiosis?

Back

Meiosis involves 2 rounds of division.

Front

At the end of which round of meiosis is the cell haploid?

Back

The cell is haploid at the end of Meiosis I.

Front

What type of inheritance is characterized by one dominant allele masking the effect of a recessive allele?

Back

Autosomal Dominant inheritance.

Front

Which macromolecule is responsible for carrying genetic information?

Back

Nucleic Acids carry the genetic code.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells have one set of chromosomes, while diploid cells have two sets.

Front

What is the role of meiosis in sexual reproduction?

Back

Meiosis produces gametes (sperm and eggs) with half the number of chromosomes.

Front

Define autosomal recessive inheritance.

Back

Autosomal recessive inheritance requires two copies of a recessive allele for the trait to be expressed.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in traits.

Front

What is the significance of crossing over during meiosis?

Back

Crossing over increases genetic diversity by exchanging genetic material between homologous chromosomes.
